Which of the following is NOT an example of a food allergen?

The correct response is based on the understanding of food allergens, which are substances that can trigger allergic reactions in sensitive individuals. Nuts, milk, and soy are all well-documented food allergens known to cause reactions ranging from mild to severe in certain people.

Salt, on the other hand, does not typically cause allergic reactions. It is a mineral that is generally recognized as safe for consumption and does not provoke the immune system in the same way allergens do. Thus, it is not classified as a food allergen, making it the correct choice in this scenario. Understanding the distinction between common allergens and non-allergenic substances is crucial for anyone involved in food service or handling, as this knowledge helps in ensuring the safety of individuals with food allergies.
